When I went looking for a 91/38 for my collection I decided I wanted one that was a little different from the rest, and this is what I found. It has all the regular Czech arsenal stamps on the reciever, plus something I had yet to see on one of these, a WW1 Austrian capture arsenal stamp, "Wiener Waffen Fabrik" . It is in what appears to be a Russian M38 war time stock ( all I have seen are in M44 stocks) except the only markings on it don't appear to be Russian or Czech.
All in all I am quite pleased with its addition to the collection.
